It's a theoretical simulation, so the results is strongly correlated to the starting assumptions and starting experimental/theoretical data-set that was chosen when making the simulation. They didnt go much in details into the paper, but based on the reported results (and on the point that the thermal transfer efficiency in the simulation is in the range of 0.0X %), it does not seem to have any real practical application fusion wise.

Anyhow it is a nice paper and I am sure some one will take the challenge to test it in the lab to see if the experiments will mirror the simulation of if any interesting differences will arise.

This sounds a little bit like the paper I referenced . Lasers might start to get interesting as the pulse width starts to approach the wavelength.

The daylight is uncomfortably bright for eyes so long in the dark.

As long as they need to have huge lasers and a gold plated hohlraum, I seriously doubt that this is the path to economic fusion reactors.

This talk of a very short coherent light pulse driving implosion has me pondering monopulse millimetre wave driven implosion, the longer wavelengths being far easier to generate efficiently. I'm also reminded that you can't "comb a hairy ball flat", suggesting a not entirely symmetrical implosion.

One arrangement that comes to mind involves filling a circular waveguide with fusion fuel then firing through a transverse magnetic microwave pulse to ionize and compress the fuel.

One drawback to photon electric field driven implosion is the electrons being driven the opposite direction from the ions.
